The Festival of Riḍván, termed by Bahá’u’lláh the “Most Great Festival” and the “King of Festivals”, commemorates the 12 days that Bahá’u’lláh spent in the garden of Riḍván outside Baghdad. The festival commemorates Bahá'u'lláh's public declaration of His mission to His family and closest followers. The first, the ninth, and the twelfth days of Riḍván are Bahá’í Holy Days on which work is suspended.
